Aim: I aim to find out whether changing the surface area of the wings on my helicopter will change the rate of it's descent. Apparatus: I will need: Paper, scissors, stop clock, metre ruler. Prediction: Air resistance is a force that acts upon any object falling through the air. It slows the rate of descent on an object with any surface area. Scientific research has found that by altering the object's surface area, the amount of air resistance either increases or decreases, changing the rate of descent. Newton's third law states that for every action there is an equal and opposite reaction. My helicopter will fall to the ground because of the gravitational pull of the Earth. In reflection to Newton's law, the opposite force in the case of my experiment will be air resistance. As gravity is pulling my helicopter to the ground, air resistance is pushing up onto my helicopter, slowing its rate of descent....
